Languages and Process Calculi for Network Aware Programming - Short Summary -

We describe motivations and background behind the design of Klaim, a process description language that has proved to be suitable for describing a wide range of applications distributed over wide area networks with agents and code mobility. We argue that a drawback of Klaim is that it is neither a programming language, nor a process calculus. We then outline the two research directions we have recently pursued. On the one hand we have evolved Klaim to a full-fledged language for highly distributed mobile programming. On the other hand we have distilled the language to a number of simple calculi that we have used to define new semantic theories and equivalences and to test the impact of new operators for network aware programming
